Automatic Backflush Filters

The fully automatic backflush filter has proven itself in numerous industrial applications as a process-reliable, high-performance and by and large maintenance-free blackflush filter system. Employing the concept of fully automatic backflushing of the filter cartridges, the filter cleans itself during the ongoing filtration process with no iterruption of operation. The exceptionally reliable technology and construction of FAUDI fully automatic backfluh filters has also proven itself in the most demanding conditions found in numerous offshore installations. We are able to complement our standard sizes with their welded construction as needed with project-specific products using the ideal material, coatings and controls – all tailored to your use case or the customer specifications, standards and norms required.

The fully automatic backflush filter has proven itself in numerous industrial applications as a process-reliable, high-performance and by and large maintenance-free backflush filter system. Employing the concept of fully automatic backflushing of the filter cartridges, the filter cleans itself during the ongoing filtration process with no interruption of operation. A portion of the volumetric flow that has already been filetred or a (supplemental) flushing medium is used for backflushing. The dimensioning of module filter systems is tailored to your use case, for example, with custom shapes and dimensions as well as other materials and customer specifications

Application area

• Refineries (protection of reactors for further processing)
• Petrochemical industry (refining of fuels)

Filtration capacity
This is dependent on the filter size and the filter medium. The modular design makes it possible to adapt the filtration capacity to suit individual needs. Filtration capacities from 15m3/h to 500 m3/h are possible

Advantages

• Increased cost-effectiveness in fuel production processes
• Enables production of lighter fuels meeting increased environmental protection requirements.
• Fully automatic, continuous production process thanks to fully automatic backflushing for regeneration/cleaning of the filter elements.
• Optimal combination of longevity, high contaminant holding capacity and minimized backflushing losses
• Unsurpassed flexibility with respect to flow rate, contaminant amount and changing future requirements thanks to its modular design
• Durable and low in maintenance

Employing the concept of fully automatic backflushing of the filter cartridges, the predominantly maintenance-free module filter cleans itself during the ongoing filtration process with no interruption of operation. A portion of the volumetric flow that has already been filtered is used for backflushing. Before cleaning, an inert gas (e.g. nitrogen) is used to build up a pressure reserve in the module that is to be cleaned. The subsequent cleaning by means of flow reversal then takes place with the pressure created using the inert gas. The dimensioning of module filter systems is tailored to your use case, for example, with custom shapes and dimensions as well as other materials and customer specifications.

Jet pulse filters belong to the group of regenerable cartridge filters. The manner of cleaning employed for these filters is that of jet-pulsed pressure cleaning. Cleaning in jet-pulse filter systems is accomplished using an intense compressed-air or inert-gas pressure impulse which reverses the flow direction abruptly in the individual filter cartridges or banks of cartridges thereby causing the filter cake to be released. The flow through the filter media (e.g. hoses or cartridges) moves from the outside inwards during the filtration phase; a supporting frame provides the element with the necessary stability. Depending on the contaminant or dust load, the cleaning takes place by means of a pressure pulse, typically controlled by the measurement of the filter’s differential pressure. The dimensioning of the jet pulse filter systems is governed by the project specifics and is thus matched to your use case, for example with custom shapes and dimensions as well as materials and customer specifications

Application area

• Separation of solid particles from gas flows
• Regenerable gas filtration
• Process dust removal
